Drawing Stereoscopic 3D images... Could it be done?

Migrated topic.

I have been fascinated with Stereoscopic 3D images for a long time now.
I've been aspiring to make my own stereo pairs of 3D images for viewing in a self-made,
panoramic 360 degrees images in 3D, but since I have a pretty low budget the
2 obvious options are out of reach:

-Buying a 3D camera.
-Buying a proper PC and using a 3D program.

That is why I've been pondering on a new Low-tech, low-budget way of creating
Stereoscopic 3D Images and I couldn't help but wonder:

Would it be possible to handdraw accurate, proper Stereoscopic 3D image-pairs
using only Perspective & Geometry?

I was thinking: Suppose you drew a scene of a courtyard(for example) using a simple
1 point perspective. Then you would measure the exact distance between the centers of the pupils of both your eyes. Then you would have to draw almost an exact copy of the 1st drawing, the only difference being that the vantage point in the 2nd
drawing is just slightly to the right of the vantage point in the 1st drawing. The
distance between these 2 vantage points should be the exact distance between your
2 pupils' centers, as measured before.

Sounds almost too easy, but I´m guessing it´ll take a little more than just that
to create accurate, properly 3D Stereo pairs. I understand that´s where a little
geometry & math can help getting the shift in perspective JUST right.


But I have a chaotic mind and, despite my rising interrest in math, I have allways
suffered from discalculia. That's why I am asking a little help here.

Perhaps someone who is more skilled & organised at math & geometry than I am can help figure out what it would take to draw a scene & determine what that scene would look like if the vantage point was shifted, for example, 6,75 Centimeters to the Right?

Please help me figure this out. Anyone?
 
I'm pretty sure you can get a Photoshop plugin to do the shift for you.
If you make an image and scan it in...the stereoscopic effect is just a click away.

Really? Is that a standard function of Photoshop? Or would I need to get it seperately?
And would it yield proper 3D images when viewed through a stereo-viewer?

Type 'stereoscopic plugin photoshop' into Google.....there seem to be quite a few.

Thanks. I'm surprised by how colorfull the red-cyan anaglyph from the 1st link is.
However I'm doubting this method would yield proper 3D-looking Stereo Images, since
it lacks the visual information of the differing perspectives of each eye.

I imagine it would turn a 2D image into an vague image with a slight 3D ish effects,
but I don't see how this method could create accurate, proper 3D Stereo images.

I want to go for as stunning a 3 Dimentional effect as possible on a low budget.
Also I want the image to be as clear as possible. Not vague & double.

That's why I want to try to develop a handdrawn perspective method for drawing stereo pairs.
To get the kind of Depth perception you get from ViewMasters & 3D movies, which cannot be achieved by simply doubling an image and shifting it slightly to the Right.

I'm sure it can be done the old fashioned way, using perspective & geometry. Just need help figuring out exactly how. Perhaps I shoud start with a simple drawing of a Cube on a plain
& try to figure out how to draw the same cube-scene from 6,75 cm to the right.

Still any help developping this handdrawn stereo pair-method would be very much appreciated.
